GOGGLES.

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed February 16- 1907- Serial No. 357.732.

- whichthe following is a full, clear, and exact description.

My invention relates to goggles or gogglettes, and includes several features of im provemeut-by which a plurality of stock parts may be assembled in different ways to obtain entirely different forms or types of product, among them a form of goggles havmg a mask of leather or flexible material, and also forms having the usual separate eye-pieces, with cushions connected by a chain, or the like. In all these forms I furtheraim'to have the glass or window removable and interchangeable, so that darkened, colored or prescription glasses may be uickly'substituted for one another, within t 1e same frames or holders.

It is further an object of the invention to have the parts easily assembled and securely fastened when in proper relation. without the use of clasps, hooks, springs, or special fastening devices of any sort.

Finally it is an object of the invention to provide for adequate ventilation of the interiorchambers, and to obtain particularly ventilation of such a character that the in terior moisture-laden air is sucked out or Withdrawn and carried away in normal use.

\Vith these and other objects in. view the invention consists in the features of construction and combination hereinafter set forth and claimed.

In thedrawings: Figure 1 is a front view' of a pair of mask goggles embodying the principles of my invention; Fig. 2 is a view partly in section of the same, being taken generally on the line II-II of Fig. 1, looking downward; the parts are detached or slightly separated in this figure; Fig. 3 is a detail sectional view showing the parts assembled to form an eye-piece of slightly different form; Figs. 4 and 5 are respectively plain and prescription glasses which may be interchangeably inserted in the goggles; Fig. 6 is a detail sectional view on the line VIVI of Fig. 1. Fig. 7 is a sectional view on line VII-VII of Fig. 6 looking in the direction of the arrows; in this figure, the usual glass is removed.

On account of the great variety of styles which are in common use, with respect to forms of masks and cushions for goggles, considerable inconvenience is caused to the manufacturers, to the dealers, and to the public. In winter, mask's of cloth or flexible leather are preferred for the sake of the warmth, but in summer many persons would rather have the eye- )ieces entirely separate, and eaeh'fiexibly cushioned so as to fit nicely upon the face of the wearer. The ladies styles are different from the mens, and in some cases the color of the mask or fabric has to be accorded to the dress of the wearer. Still further inconvenience sometimes arises on account-of the requirements for darkened, colored or lens glasses for persons'with defective eyesight to avoid the necessity of separate spectacles. The lens glasses are ordinarily termed prescription glasses in the art. The necessity of having so many styles of goggles increases the expense and. necessitates a large stock being carried by the deal-- ers. Moreover the purchaser cannot alter hereinafter described, to obtain the different kinds of goggles, and to enable the-insertion of different kinds of glasses. The inner frames 1 are made of springy material, preferably steel, of oval outline, with external and internal rims 2 and 3, on the inner and outer edges respectively. The internally extending rim 3 is interrupted for a certain distance at the spaces 4;, along opposite sides of the frame, and the metal at these spaces is embossed inward, as clearly shown in Figs. 2 and 3. The purpose of'embossing the metal inward in this way is two-fold, as will later appear. I

secured. .1 have already alluded to the mon and essential element of all the forms of l the invention hereinafter described. The outer frames are connected or assembled in pairs by means of a chain 6, and the pair thus formed: is adapted to be assembled with to cushions, or to any other form or style of sup ort. The outer frames 5 have internal y extending rims 7, somewhat similar to the rims 3 of the inner frames 1. The outer frames also have different zones or diameters, as shown at S and 1), the two zoncsor divisions being separated by a ledge 10. The size and form of the inner zone 9 is such as to closely receive the inner frame 1.. The

acconnnodate the rim 2 of the inner frame 1.. The outer frame also has a plurality of punched openings 11, which, however, are screened by the metallic lugs 12, formed by the metal which is displaced or embossed outward from the openings 1.1, and it will be observed that the screens 12 are inclined inward or toward the face of the wearer in use.

The glasses are received between the inner frame 1 and the outer frame 5, as clearly shown in Fig. 2. When ordinary glass panes or windows 13 (Fig. 4), are used, it is not necessary to have special frames, but in case of prescription glasses 1.4 (Fig. 5), it is best to have these surrounded by their own special rim or frame 15. In any case, the glasses are closely held between the rim 3 of the inner frame 1 and the rim 7 of the outer frame 5..

Before taking up the interchangeable charconsider the use of the foregoing and the manner In which effective ventilation is springyLcharacter of the inner frames 1 and the depressed rtions 4. thereof. The inner frames 1 makes; tight fit in the outer frames, but if the inner frames are grasped and pinched slightly, at the portions 4, they are collapsible enough so as to spring easily into the outer frames. When they are in place, their natural resiliency causes them to expand tightly into position. Thus the inner and outer frames with their contained glasses are tightly and firmly assembled in use, and without the use of clasps, hooks, springs, screws, or other similar and inconvenient contrivances. Not only does the "depressed portion 4 thus furnish the means by which the frames are assembled and secured together, but it also develops an air space or chamber which has an important function in the ventilation. This is best shown in Fig. 6, from which it will be seen that the depression of the surface 4 produces a chamber 16, immediately adjacent to the openings 1.1 of the outer frame. 17 indicate openings in the inner frame, which connect this chamber devices. outer frames 5,

This is an important consideration in the practical use of the invention.

1 will now consider the interchangeability features of the invention.

In Figs. 1 and 2, the innerframcs 1 are shown attached to a flexible mask 18. 1.11 Fig. 3 the inner frames are shown attached to a rubber cushion-19. It is evident that the inner frames are capable of being attached to any desired mask or device. For this purosc the rims 2 are used it convenient, and. if not, are simply cut oil, filed away, or omitted, as shown in Fig. 3. A purchaser with masks 18, rims 19, etc, all having the inner frames 1. thereon, may assemble his different masks with a single pair of outer-frames 5, to form any desired kind of goggles. At all times he is enabled to insert or replace new glasses 13 or 14 in case 'ofbreakage, or in case a change is d'esire'dfor any reason.

A feature of the invention lies in the means for the attachment of straps and fastening 20 indicate. lugs or cars upon the and it is evident that an elastic band or strap may be attached to these ears so as to bind the goggles upon the head of the wearer. In View of the fact that the ears are on the outer frames, they are always present, no matter with what mask the outer frames are assembled. A further very important point in thisconnection is that since it is the outer frames whichare secured by the band or strap, there is no possibility of the parts becoming disassociated or disassembled in use, because the parts are locked in place by the band as long as.
